$(8 x - 4 - 4 x^{2}) + (7 x^{2} - 9 x - 6)$

Step 1

Remove parentheses.

$8 x - 4 - 4 x^{2} + 7 x^{2} - 9 x - 6$

Step 2

Subtract $9 x$ from $8 x$ .

$- 4 - 4 x^{2} + 7 x^{2} - x - 6$

Step 3

Subtract $6$ from $- 4$ .

$- 4 x^{2} + 7 x^{2} - x - 10$

Step 4

Add $- 4 x^{2}$ and $7 x^{2}$ .

$3 x^{2} - x - 10$

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
